TYPE-WRITING MAGHINE.

Specification of Lettera Patent.

Eatented April 13, 19.09.

Application filed September 26, 19116. Serial No. 336,341.

To all whom it mag; remera.' Y

Be it known that i, .loser franz Foa- Kanrii, a citizen of the Empire ofAustria- Hungary, and resident oit innsbruck, in the Empire ofAiistria-Hungary, have invented a certain new and useful improvement inType-Writing Machines, of which. the tollowing` is a specification.

My invention relates to type-Writing inai chines, and its object is toprovide improved nit-aus for enabling the operator to write certainclairacters or symbols at regular distances above or below the generalline of impression when required, as is sometimes the case, forinstancer` when writing fractions or certain characters oi reference,such as :n3 or 2h (Where thenuineral 3 and the letter h require to bewritten somewhat raised), or when Writing atoniic symbols,

C2 (Where the numeral 2 requires to' be Written farther below).l Iattain this object by means of. the mechanism hereinafter described andshown in the accom! panying drawing as applied to the paper Vroller of atype-Writing inaehine of the well Vl/rnown Hammond system.

in the accompanying drawing illustratingmy invention Figure l is anelevation show ing my' improved mechanism' as it appears when lookingupon the end'o, 'the paper roller of a type-Writing machine. F i g. 2 isa view as seen from the right hand side of Fig. 1,Witli pai-ts brokenaway and other parts omitted. Fig. 3 is an elevation of the sainemechanism viewed from the opposite side to that shown `in 1 with partsomitted. Fi 11's and 5 show details of the mechanism in'elevation withthe parts in different-positions, some other parts being omitted. Fig. 6is an end view of a detail to be described. Fig; 7'- is a side view ofthe roller arm. S is side View of the brake arm. i f A. is the usualpaper roller .of vthe type- Writing machine. E is one of the Side parteof the carrier traine F npporting the said paper roller and mounted onthe frame part D.

B is a disk having rounded teeth or eorrug-ations on its periphery andsecured to o1: formed on the paper roller A at one end of the latter.

. C is an elevated peripheral portion formedl on or applied to the paperroller near the disk B and consisting either of the saine material asthat of the paper roller or o any suitable metal.

Secured to the carrier part E, preferably by screws as shown, is a frame8 provided at. its Banged outer end with a longitudinal guide slot bhaving a lateral recessed por-y tion or notch b', as more clearly shownin the end vieu' ot this part, Fig. "6. An angular lever l mounted toturn on the journal oraxis ot the paper roller A extends with its upperarm i through the guide slot b, as shown in Figs. i and 2. This leverarm l is formed as a spring exerting a slight lateral pressure Withintheguide slot so as to drop into, and securelyengage in, the notch bwhen moved into position opposite the latter. The opposite or lower armof the said lever 1 has screwed thereinto, or otherwise secured thereto,a pin 7 on which are fulcrurned an arm 3 and a brake alni 4.-, theformerfhaving a. roller 2 adapted to engage the Vteeth or corrugationsoi' the disk B upon the arm being suitably turned on its pin 7, and thebrake arm 4 extending toward the elevated periphe 'al portion C of thepaper roller A so as to be brought into engagement therewith upon the.said brake arm 4 being suitably turned on the pin 7. A'spring 6surrounding' the hub portion of the lever l restswith its one endagainst a screw 6 and presses with its other end against a lug 3" formedon the aiin thereby acting to firmly press the roller Q of the said arminto en gageinent with the teeth or corrugations of the disk` B and tothus securely hold the' paper roller in the respective positionsdetermined by the interstices of the said teeth or corrugations.

The arm 3 has tulcrumed to it a small hand lever 5 4the lower end ofWliie', as shown in Fig. 3, has a rectangular ben foji -oonvenience inhandling. A cam portion 5 l formed on this hand lever is received Withina notch or recess il provided in the brake' arm 4. Thus, when the handlever is turned upward so asrto thereby raise thebrake arm 100.

li, the upper curved portion of the latter will first engage theperipheral portion C of the paper roller and, in the further rotation ofthe cani portion 5'., the roller 2 of the arin 3 will be raised awayfrom, and out of en- 105 gagenient with, the teeth or eorrugations oftheclislt B, so that the paper roller will then be held in position bythe brake arm of. the said lever in opposite direetiens i and not anylonger hy the roller 'llii position oi the parts is shown in l 1g. o.

Upon the hand lever o being then lowered h g lever m an intermediateposition, substanagain the roller 2 will iirsl return into engagement`.viili tlieteeth or eorrugatlions of the did; l, aud'then the liraliearni Al will recede from and releasex the paper roller. ee Fig. i. luthis ivise the paper roller is, by means of the arm l) and its roller 2on the one hand and liv means oi' the brake arm si on the )ther hand.,broughtv into suoli relation `with the angular lever l that the paperroller must always follow any adjusting movement imparted to the Saidlever 1n the one or the other direetion. i iienee, When the operatordesire to so adjust the posit/ion of the paper roller as to Cause thepoint of impression on the sheet of paper to come a little above theusual line o impression he will' raise the leverl arm l outy of thenoteli o and mm e. it to one end of the guide slot (D` Whereas when hedesires to bring the point, oi' impression a little helow the usual lineof impression he will nieve the said lever arm to the other end of theguide Slot. in order to then continue on the usual line oi' impressionagain the operatm' will return the lever arm i into engagement with thenoteh b What i claim as my invention, and desire lo seeure by Lettersiatent is:-

i. ln a type-writing machine the eoniliination, with a paper feedroller, of a line adjustiner lever for turning said roller in eitherdirectioin'ineans for limiting the movement and means for bringing thesaid lever into and Nout of operative engagement with the said paperfeed roller, substantially as and for the. purpose dewrilied. l
